Sterling Seal & Supply Style 9000 304 Stainless Steel Spiral Wound Gaskets with Flexible Graphite Filler are for applications with high temperature variations (thermal cycling),and/or pressure variations, and/or flange rotation problems etc, They are used where gaskets with adequate residual stress (stress retention),flexibility and recovery are needed and have been designed to meet these demanding requirements Spiral-wound gaskets are made of a preformed metallic strip and a soft filler material, wound together under pressure, and optionally with an inner and/or outer guide ring The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and recovery A v-shaped crown centered in the metal strip acts as a spring, giving gaskets greater resiliency under varying conditions Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter Spiral winding (sealing element) consists of metal and soft filler material These gaskets are durable, easy to install and easy to remove Resiliency and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications Widely used throughout refineries and chemical processing plants, spiral wound gaskets are also effective for power generation, pulp and paper, aerospace, and a variety of valve and specialty applications Sterling Seal & Supply Style 9000 - 304 Stainless Steel Spiral Wound Gaskets are a precision-engineered sealing solution for flat and raised face flanges and flanged joints. Carbon Steel outer ring Style 9000 gaskets supplied by Sterling Seal & Supply are also suitable for heat exchangers, boiler hand holes, manholes, and other high-temperature, high-pressure applications Gasket Identification Markings Required by ASME B16.20 clearly Etched in all gaskets. These gaskets excel in the prevention of flange erosion, inward buckling and reduction of turbulent flow Installation Tip: Spiral Wound Gaskets with internal or external guide rings should be fully compressed to the guide ring. This will not damage the gasket or affect the sealing performance Installation Tip: Check that flange faces are clean and in good condition. Ensure correct bolting material is utilized to suit the operating conditions, and the use of bolt lubrication is employed Brand Lamons Color Yellow with Grey Stripe Model SSI90002500304GR2500X6 Size Name 2.5 Unit Count 6.0 Count Part Number SSI90002500304GR2500X6 Manufacturer Lamons Item Diameter 2.5 Inches Material Type 304 Stainless Steel Windings, Graphite Outside Diameter 6.63 Inches
